SALTO XS4 SENSE

Salto XS4 Sense Smart Energy Management System

XS4 Sense is a smart energy management solution from Salto Systems, designed forhotels, student dormitories, ship cabins, and office spaces,using wireless sensors and controllers to automatically adjust energy use based on occupancy. It prevents air conditioning and lighting from running needlessly, reduces energy waste, provides quantifiable energy-saving data management, and integrates with SALTO access control systems.

4 Common Problems with Current Sensing Systems

▲ Current solutions don't truly achieve smart energy savings: HVAC ON, Lights ON, Open Window — an open window lets cooled air escape

1/4 Occupancy Detection

Traditional systems rely on a room key card to activate power, offering only basic power control and incompatible with the growing trend of digital keys. This not only affects user convenience, but also fails to guarantee that lights and air conditioning turn off automatically when a room is empty, resulting in energy waste.

2/4 Installation Complexity

GRMS systems require complex, disruptive construction work, making deployment in new buildings and retrofits of existing ones both difficult and costly, resulting in poor payback and higher ongoing maintenance costs.

3/4 Wireless Integration Challenges

Integrating GRMS and wireless energy management systems with access control remains challenging; existing solutions often lack flexibility and compatibility, making cross-device or cross-brand integration difficult.

4/4 Difficulty Verifying Energy Savings

Traditional approaches mostly estimate energy savings by comparing overall electricity bills or floor-level usage, lacking per-room, real-time monitoring data. This makes it hard to objectively demonstrate benefits or make further optimizations.

Product Features

Fully Wireless, Fast Installation: Designed as a global SALTO platform, XS4 Sense integrates easily into existing buildings via Wi-Fi and BLE (Bluetooth Low Energy), requiring no large-scale construction — fast to deploy and highly flexible.
Energy-Saving Control, Maximizing Energy Efficiency: Smart in-room energy automation uses PIR motion sensors, door/window detectors, and access event triggers to automatically manage lighting, air conditioning, and HVAC systems, reducing energy waste and optimizing consumption in real time.
Scalable, Cloud-Based Management Platform: Supports remote monitoring, device configuration, and energy analysis. The system provides real-time monitoring, energy consumption analysis, and energy-saving reports (such as CO2 reduction, kWh saved, and tree-equivalent values), and is compatible with the SALTO Space access control platform.
Sustainable Energy Savings, Meeting Global Energy Standards: Built around sustainable design and compliant with international energy-efficient building codes, helping businesses implement energy management and meet ESG goals.

How Does It Work?

Mobile App

XS4 Sense is an app-centric solution with 3 main functions:

Dashboard

Monitors energy savings and consumption across the entire installation
Can be filtered by room and date for more detailed information

Real-Time Energy Status

View the equipment and energy-saving status of each room

Setup and Pairing

Create, edit, and delete all devices across the installation
Assign controllers to each room
Pair multi-sensors and door/window sensors to controllers

Deployment Modes

Three modes are available to match site needs, deployable at any scale.

Mode	Features	Architecture
Smart Standalone	Works offline and standalone, no network required — the app is used only for pairing.	Controller + Sensor + App
Online	Real-time cloud monitoring, bridged via a Local Appliance.	Controller + Sensor + App + Cloud and Local Appliance
Online Connected	Integrates with Salto Space (BAS protocol, BLUEnet), supporting digital keys.	Controller + Sensor + App + Cloud + Salto Space

The SALTO Ecosystem

SALTO has long focused on access management technologies such as access control, electronic locks, and mobile keys. Now, as demand for smart buildings grows, it is extending its capabilities into energy-saving devices and sensor integration.XS4 Sense isn't a standalone product — it's part of what strengthens the SALTO smart access platform.

The smart building of the future is no longer just about managing "who can enter" — it's also about "how energy is used." By integrating sensors, energy monitoring, and automated control, access control, power control, and energy management are brought together on a single platform.
